Hybrid laparoendoscopic single-site (LESS) pyeloplasty: Initial experience in children.

BACKGROUND AND OBJECTIVE: Mini-invasive surgery is still evolving to get better surgical conditions for patients with ureteropelvic junction obstruction. We used technical modifications (hybrid pyeloplasty) that simplify surgical steps of laparoendoscopic single-site pyeloplasty in children. Our aim was to compare hybrid pyeloplasty to laparoendoscopic single-site pyeloplasty and to open pyeloplasty. PATIENTS AND METHODS: We retrospectively reviewed records of patients with ureteropelvic junction obstruction aged<14years undergoing pyeloplasty at our institute from January 2011 to December 2015. Demographic data, laterality, operative time, length of hospital stay, drainage tubes, and postoperative complications were recorded. Surgical outcomes were evaluated based on renal sonography and Lasix diuretic renography. RESULTS: Among 38 patients, 17 underwent open pyeloplasty (group I), 10 had laparoendoscopic single-site pyeloplasty (group II) and 11 had hybrid pyeloplasty (group III). The mean age at the time of operation was 55 months. The operative time in group III was significantly shorter than that in group I and group II (P<0.001). The shortest median hospital stay was noted in the group III. The mean follow-up period was 26 months (range: 6-52 months). CONCLUSION: The hybrid pyeloplasty using LESS combine the successful outcomes of open surgery and advantages of minimally invasive surgery. It offers small incision surgery, good working space, short operation time, secure anastomosis and good cosmetic results. LEVEL OF EVIDENCE: 5.

Clinical outcomes of iris fixation and sutureless scleral fixation of dislocated foldable posterior chamber intraocular lenses.

PURPOSE: Explore the visual outcome and complications of iris fixation intraocular lenses (IFIOL) and sutureless scleral-fixated intraocular lenses (SSFIOL) in the surgical management of patients without exchanging dislocated posterior chamber intraocular lenses (PCIOLs) in the vitreous. METHODS: Retrospectively, 14 IFIOL and 15 SSFIOL reimplantations for dislocated PCIOLs were analyzed. Mean follow-up of reIFIOL group and reSSFIOL group: 11.3±2.0 (range: 9-15) months and 11.8±2.2 (range: 9-16) months, respectively. Preoperative and postoperative outcomes, operative indications, and complications were evaluated. RESULTS: Primary surgical indications were pseudoexfoliation (PXE) (21.4%), post-cataract surgery (PCS) (35.7%), trauma (42.8%) in the reIFIOL group, and PXE (26.6%), PCS (40%) trauma (33.3%) in reSSFIOL group, respectively. At the latest follow-up, there was an improvement in best-corrected visual acuity (BCVA) (0.053±0.051 to 0.53±0.13, P<0.0001) in reIFIOL group and (0.05±0.02 to 0.64±0.16, P<0.0001) in reSSFIOL group. Postoperative complications of reIFIOL group and reSSFIOL group included corneal edema (14.2%; nil), IOP elevation (21.4%; 7.1%), bullous keratopathy (14.2%; nil), anterior uveitis (35.7%; 13.3%), cystoid macular edema (CME) (21.4%; 7.1%), pupil ovalization (21.4%; nil), broken haptic (none; 13.3%), IOL exchange (nil; 13.3%), and vitreous hemorrhage (nil; 14.2%). CONCLUSIONS: Self-dislocated IOL reimplantation may enable much earlier visual rehabilitation in the reSSFIOL group than in the reIFIOL group. Moreover, the 27G trocar-assisted reSSFIOL technique takes a shorter operation time and relatively lower complication rates. However, further prospective studies with larger series and longer follow-up periods are required.

Incisional hernia after robotic single-site cholecystectomy: a pilot study.

PURPOSE: Robotic LaparoEndoscopic Single-Site Surgery Cholecystectomy has been performed for 5 years using a dedicated platform (da Vinci® Single-Site®) with the da Vinci® Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA). While short-term feasibility has been described, long-term assessment of this method is currently outstanding. The aim of this study was to assess long-term parietal complications of this technique. METHODS: In this retrospective study, patients operated between 2011 and 2013 were evaluated. Parietal incision was assessed with ultrasonography and patients screened for residual pain from scar tissue. Demographic and perioperative data were also collected. RESULTS: We evaluated 48 patients [38 female, 79.2%; median age 49 years (range: 24-81 years)]; mean BMI 25.9 kg/m2 [±SD 4.1 kg/m2]. After a median follow-up of 39 months (range: 25-46 months), six incisional hernias (two patients had a positive echography but a negative clinical examination) were found (12.5%, 95% CI 7.5-30.2), and two patients had a surgical repair. The overall rate of incisional hernia was 16.7% (95% CI 7.5-30.2). Residual pain was observed in 5 of 48 patients. CONCLUSION: This preliminary study suggests that a clinically significant rate of incisional hernias can occur after R-LESS-C. Larger studies comparing R-LESS-C to alternative methods with long-term follow-up are necessary.

[Bowel injuries after port insertion in laparoscopy. Gynerisq's database analysis]. / Plaies digestives à l'insertion des trocarts en cœlioscopie. Analyse de la base de données de retour d'expérience de Gynerisq.

INTRODUCTION: Port insertion is a high-risk period during laparoscopy. The French Gynecologist and Obstetricians College (CNGOF) published recommendations in 2010 to minimize those risks. The aim of our analysis was to establish the accidents' circumstances and consequences and to determine if those incidents could have been depending on whether recommendations had been respected or not. MATERIAL AND METHODS: Gynerisq is an approved organism by the Haute Autorité de santé (HAS). Its mission is to evaluate and improve practices by a risk management centered approach. We analysed incidents reported by Gynerisq's adherents in an experience report database. RESULTS: Above 114 incidents analysed in the Gynerisq's database, we reported 31 bowel injuries. Those injuries occurred for 77.4% (24/31) during planned interventions. For 32.3% of the cases (10/31), interventions were judged complex by the surgeons. A total of 54.8% (17/31) of the patients had a history of laparotomy. Above 27 injuries occurred during Veress needle or open laparoscopy, 17 could have been avoided regarding to the surgeon. The causes reported were in 10 cases that the recommendations had not been respected, in 2 cases another cause and in 5 cases no causes were given to explain the incident. CONCLUSION: Our analysis shows that bowel injuries after port insertion, in open laparoscopy or Veress needle use, do not seem to occur only in an emergency context or during complicated interventions. However, most of the incidents occurred for patients with risk factors.

A survey of percutaneous chest drainage practice in French university surgical ICU's.

OBJECTIVE: Percutaneous chest drainage guidelines were published in 2010 by the British Thoracic Society. On several points (insertion technique, drain size), they seem to differ from French practices. Our objectives were to evaluate practice of pleural drainage in French University surgical intensive care units (ICU's), and to compare it with the British guidelines. STUDY DESIGN: National phone survey. METHODS: Physicians working in 58 ICU's were surveyed first in 2007, and subsequently in 2012. They were read a questionnaire to evaluate the demographic characteristics of their units, their indication for pleural drainage, how they quantified pleural effusion, and their technique for drain insertion. Data from the two surveys were compared to detect an evolution in practice following the publication of the British guidelines. Results are expressed as the mean response. RESULTS: In 2007, pleural drainage indications relied on various respiratory criteria in 91% of cases (versus 95% in 2012) and/or on pleural effusion volume in 71% of cases (versus 59% in 2012). Trocars (Monod or Joly) were used in 68% of the procedures in 2007. In the rest, either blunt dissection, a Pleurocath® or the Seldinger technique was utilized. From 2007 to 2012, the Seldinger technique increased in frequency (10% versus 22%, P=0.005) while Monod trocar usage decreased (41% vs 29%, P=0.012). Ultrasound before pleural effusion drainage became nearly systematic in 2012 (60% vs 86%, P<0.001). CONCLUSION: The frequent use of trocar (and therefore of large drains) for pleural drainage in French ICU's differs significantly from the British guidelines.

[Salpingo-oophorectomy by laparoendoscopic single-site surgery for everybody]. / L'annexectomie par cœlio-chirurgie mono-trocart pour tous.

OBJECTIVES: To study the adnexectomy by laparoendoscopic single-site surgery with conventional laparoscopic instruments, we standardised the technique of salpingo-oophorectomy. PATIENTS AND METHODS: In this prospective study, all patients with adnexectomies from June 2010 to January 2014 were included. Laparoendoscopic single-site adnexectomy with conventional instruments is described step by step in order to make it available for the majority of gynecologic surgeons. Laparoconversions and complications are also noted. RESULTS: We realized 42 bilateral salpingo-oophorectomies, 16 single salpingo-oophorectomy. The average operative time was 45min (15-120) with negligible blood losses. There were no laparoconversions and very few complications. After 15-20 adnexectomies, the procedure took less and less time. DISCUSSION AND CONCLUSION: Adnexectomy by laparoendoscopic single-site surgery procedure with conventional laparoscopic instruments is easily reproducible with standardized steps and has many advantages.

[Single-port surgery and adnexal procedures: which indications in oncological surgery?]. / Cœlioscopie par mono-trocart et chirurgie annexielle : quelles applications en chirurgie oncologique ?

OBJECTIVE: To show the interest of single trocar in order to perform uni- or bilateral salpingo-oophorectomies. PATIENTS AND METHODS: A descriptive study monocentric. RESULTS: A total of 79 unilateral or bilateral salpingo-oophorectomies were performed by single-port laparoscopy between January 2010 and September 2012 at the Institut Paoli-Calmettes (Marseille). There are three surgical indications: diagnostic, therapeutic and prophylactic. The median age was 50 years (22-78 years). The median BMI was 22.4 kg/m(2) (17.5 to 37.7 kg/m(2)). The median blood loss was 0cc (0cc-50cc). The median hospital stay of patient was one day (0-6 days). The conversion rate in this study was 8.8%. DISCUSSION AND CONCLUSION: The single-port laparoscopic approach to perform uni- or bilateral salpingo-oophorectomies is a natural evolution of the conventional laparoscopy. If the cosmetic role seems obvious, its therapeutic value compared to traditional technique must be demonstrated by prospective studies with larger numbers.
